Overall Survival [ Time Frame: From randomization of the first subject until the database cut-off approximately 14 months later (19May2010 - 21Jul2011) used for 2nd planned formal interim analysis (IA). ] [ Designated as safety issue: No ]

Overall survival (OS) was defined as the time (days) from randomization to death due to any cause. Patients alive at the time of analysis were censored at the last date known to be alive. If a patient was lost to follow-up and there was no contact after randomization, this patient was censored at Day 1.

Original Primary Outcome Measures ICMJE (submitted: April 13, 2010)

Overall survival [ Time Frame: From randomisation of the first subject until 32 month later ] [ Designated as safety issue: No ]

Progression-free Survival (Based on Investigator's Assessment) [ Time Frame: From randomization of the first subject until the database cut-off approximately 14 months later (19May2010 - 21Jul2011) used for 2nd planned formal interim analysis. Tumor assessed at 8 week intervals. ] [ Designated as safety issue: No ]

Progression-free survival was defined as the time (days) from date of randomization to date of first observed disease progression (radiological or clinical) or death due to any cause, if death occurred before progression was documented.

Objective Tumor Response [ Time Frame: From randomization of the first subject until the database cut-off approximately 14 months later (19May2010 - 21Jul2011) used for 2nd planned formal interim analysis. Tumor assessed at 8 week intervals. ] [ Designated as safety issue: No ]

The objective tumor response was defined as the percentage of patients with complete response (CR, tumor disappears) or partial response (PR, sum of lesion sizes decreased at least 30% from baseline) as best overall response. A best overall response was defined for all patients, using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, version 1.1. Patients whose best overall response was not CR or PR, and any patients with no post-baseline assessments were considered nonresponders for the analysis.

Disease Control [ Time Frame: From randomization of the first subject until the database cut-off approximately 14 months later (19May2010 - 21Jul2011) used for 2nd planned formal interim analysis. Tumor assessed at 8 week intervals. ] [ Designated as safety issue: No ]

Disease control was defined as the percentage of patients whose best response was not PD [sum of lesion sizes increased at least 20% from smallest sum on study or new lesions] (ie, CR [tumor disappears], PR [sum of lesion sizes decreased at least 30% from baseline] or SD (stable disease)). SD included if at least 6 weeks after randomization.

Tumor Response [ Time Frame: From randomization of the first subject until the database cut-off approximately 14 months later (19May2010 - 21Jul2011) used for 2nd planned formal interim analysis. Tumor assessed at 8 week intervals. ] [ Designated as safety issue: No ]

A tumor response (best overall response) was defined for all patients, using the RECIST criteria, version 1.1. Categories: complete response (CR, tumor disappears), partial response (PR, sum of lesion sizes decreased at least 30% from baseline), stable disease (SD, steady state of disease), progressive disease (PD, sum of lesion sizes increased at least 20% from smallest sum on study or new lesions). Clinical PD considered when radiographic imaging not possible.

This is a randomized, double-blind, placebo-controlled multi-center phase III study to evaluate efficacy and safety of regorafenib in patients with metastatic colorectal cancer (CRC) who have progressed on/after all approved drugs for CRC
